The United States' blockade of the Strait of Hormuz has pushed the global energy landscape to a new tipping point.
According to Xinhua News Agency , Trump announced on April 12 that the U.S. Navy would immediately blockade all ships entering and leaving the Strait of Hormuz, and the U.S. military officially implemented the blockade on April 13. This move came just hours after the breakdown of the Islamabad negotiations between the U.S. and Iran, directly jeopardizing the fragile ceasefire agreement reached on April 7. The Iranian Islamic Revolutionary Guard Corps immediately warned that any military vessel approaching the strait under any pretext would be considered a violation of the ceasefire agreement, and threatened to strike all ports in the Persian Gulf and the Sea of Oman if its ports were threatened.
Oil prices surged in response, with the market pricing in further supply shortages. If the blockade is effectively implemented, it will not only cut off Iran's oil export lifeline but also exacerbate the pressure on Asian countries heavily reliant on Middle Eastern energy. Here are the six core issues that investors are most concerned about.
I. What exactly is the U.S. Navy doing?
On April 12, the permanent ceasefire talks between the US and Iran in Islamabad broke down. According to CCTV International News , hours later, Trump posted on social media that, "effective immediately," the US Navy would blockade "any ship attempting to enter or leave the Strait of Hormuz," and indicated that other countries would participate, without naming them. He also threatened to "intercept all ships paying passage fees to Iran in international waters," suggesting the blockade could extend far beyond the strait itself, reaching as far as the Sea of Oman.
Compared to Trump's rhetoric, the official statement from the U.S. military was slightly narrower. The military set the start time for the blockade at 10:00 AM New York time on April 13th, applying to all "ships entering and leaving Iranian ports and coastal areas." Neutral vessels that have not docked in Iran will not be obstructed, but may be subject to inspection for prohibited cargo. The U.S. military advised crew members navigating in the Sea of Oman and approaching the Strait of Hormuz to closely monitor official announcements and proactively contact the U.S. Navy.
On April 13, the U.S. military notified shipping operators that it would intercept, drive away, or seize vessels departing from Iran. It remains unclear whether the U.S. is willing to send its own ships into the Indian Ocean to pursue oil tankers, and how the two sides will respond in the event of a potential standoff or damage to the tankers.
II. How will Iran respond?
According to CCTV News , after the United States threatened to begin preventing any ships from entering or leaving the Strait of Hormuz, Iran's Islamic Revolutionary Guard Corps issued a statement saying that any military vessel attempting to approach the strait under any pretext would be considered a violation of the ceasefire agreement. Iran also warned that if its shipping hubs are threatened, it will launch attacks on all ports in the Persian Gulf and the Sea of Oman.
John Bradford, a former U.S. Navy officer and co-founder of the Yokosuka Asia-Pacific Research Council, said, "This new escalation is more likely to trigger more confrontation than to promote reconciliation."
III. Why did the United States take this action?
Since the US and Israel launched their strikes against Iran on February 28, Tehran has been tightening its control over the Strait of Hormuz, reducing the number of ships passing through daily from about 135 in peacetime to single digits , bringing this vital waterway to a near standstill.
This asymmetric tactic has put the United States in a difficult position—Iran successfully blocked the passage of ships from other countries while maintaining its own oil exports, thus both driving up global oil prices and preserving export revenues.
The ultimate goal of the blockade is to cut off Iran's oil exports and sever its regime's key source of revenue.
The Trump administration had previously implemented this strategy in Venezuela, crippling the country's economy through blockades and sanctions. However, Venezuela is far smaller than Iran, has a limited fleet, and is far less strategically important to global oil exports than Iran.
IV. What does this mean for Iran?
If the blockade is effectively enforced, it will be a heavy blow to Iran, which is highly dependent on oil exports.
Iran has benefited from high oil prices in recent weeks – the latest data shows that Iran's oil revenues surged 37% in March. Crude oil that was previously sold at a discount was traded at a premium earlier this month, partly due to waivers granted by the United States to increase supply, allowing buyers to purchase previously sanctioned Iranian crude oil.
For Iran, which is facing severe damage from US-Israeli airstrikes and urgently needs to rebuild its economy, higher prices per barrel are crucial. Since the outbreak of the war, this extra income has accumulated to hundreds of millions of dollars. However, once the blockade is implemented, this windfall may come to an abrupt end.
V. What does this mean for the United States?
Trump has frequently linked the Middle East supply shocks to the prospects for US oil and gas exports, characterizing the crisis as a strategic opportunity for the top oil-producing nation. According to CCTV International News , Trump claimed on Monday that a large number of oil tankers are already heading to the US to load oil and ship it globally, adding that "these ships don't even need to pass through the Strait of Hormuz."
However, U.S. crude oil is not a perfect substitute for Middle Eastern oils, and for U.S. consumers, high benchmark oil prices are already driving up inflation.
Iran clearly understands that it may be more resilient than the United States in withstanding economic pressure. Oil prices surged immediately after news of the blockade broke, as investors prepared for potential supply shortages.
VI. What does this mean for Asian countries?
Asia is the biggest victim of this energy crisis, and further restrictions on traffic in the Strait of Hormuz will exacerbate the region's situation. Even before the closure was announced, the number of ships passing through the strait had already decreased significantly.
The waivers previously granted by the United States for purchasing sanctioned Iranian crude oil appear to have been nullified by the blockade, drastically narrowing the room for maneuver. Countries that had previously reached bilateral agreements with Iran may now be hesitant to expand their purchasing options for fear of a direct confrontation with the United States.
South Korean President Lee Jae-myung previously addressed the nation, urging citizens to "save every drop of fuel" and proposing a $17 billion emergency relief plan to mitigate the impact of rising fuel prices on South Korean households and businesses. Meanwhile, economies heavily reliant on Gulf energy supplies, such as India and Australia, have also implemented emergency measures.
In a Bloomberg TV interview, Jorge Montepeque, managing director of Onyx Capital Group, bluntly stated: "They're so focused on Iran that they can't see what they're doing to the whole world. The pain is in Asia, the pain is in the South Pacific, the pain is in all the oil-dependent countries."
